Patented May 13, 1952 UNITED STATES P T-gar QFFICE RUB-BOARD BRIDLE SUPPORT Harold Edwin Sparks, Temple, Okla.

Application April 24, 1950, Serial No. 157,760

2 Claims.

This invention relates to a support for a rubboard bridle of a well pump.

An object of this invention is to provide a support for the rub-board bridle of a well pump which will eliminate friction and provide a long lasting support.

Another object of this invention is to provide a support of this kind which may be withdrawn from its base when a pulling operation is performed at the well.

A further object of this invention is to provide a support of this kind which can be readily adjusted so as to provide the necessary support for the rub-board bridle and can be easily lubricated.

A further object of this invention is to provide a device which will eliminate whip in the rod line and-will prevent the bridle from breaking equipment when the rod line breaks.

With the above and other objects in view, my invention consists in the arrangement, combination and details of construction disclosed in the drawings and specification, and then more particularly pointed out in the appended claims.

In the drawings:

Figure 1 is a detailed side elevation of a rubboard bridle support constructed according to an embodiment of this invention.

Figure 2 is a front elevation partly broken away and in section of the device.

Referring to the drawing, the numeral I designates a tubular base member which is disposed in upright or vertical position and is embedded in a concrete base I I disposed in an opening I3 formed in the ground. A portion of the tubular base I0 projects above the top of the concrete foundation H, and the projecting portion of the base I!) is formed with vertically spaced apart openings I2. A U-shaped cradle or supporting member I4 is disposed above the base I0 and includes a horizontally disposed bight portion I5 with upwardly projecting legs I 6.

A tubular shank I1 is secured to the center of the bight I5 and is ada d to telescope into the base ID. The shank I! is ormed with a series of spaced apart openings I8 which are adapted to selectively register with the openings I2, and a pair of bolts I9 are extended through the openings I 2 in the base Ill and registering openings I 8 in the shanks I1.

A bearing block 20 is carried by each leg I 6 of the cradle 14 and includes a shank or plug 2| which engages within the adjacent leg I6. Each bearing block 20 is formed in the upper end thereof with a horizontally disposed recess 22 within which the end of a roller shaft 23 is adapted to rotatably engage. Shaft 23 extends across the top of the cradle I4, and the ends of the shaft 23 are rotatably and removably engaged in the recesses 22. A roller 24 is fixed on the shaft 23 between the bearing blocks 20 and is held against undue endwise movement by the blocks 29.

The roller 24 is adapted to have mounted thereon a bridle which includes a pair of bars or members 25 which are connected with the walking beam of the well pump, and the bars 25 are adapted to reciprocate horizontally on the roller 24. Each bearing block 20 may be impregnated with a lubricant and may be periodically lubricated so that the shaft 23 will freely rotate Within the recesses 22.

In the use and operation of this support, the tubular base I0 is firmly embedded in the concrete foundation II which is positioned closely adjacent the well. The shank I1 of the cradle I4 is extended into the base I0 and is vertically adjusted by extending the bolts I 9 through selected openings I8 in the shanks I1.

With a support as hereinbefore described, the bridle 25 will be firmly supported for horizontal reciprocation, and in the event it is necessary to remove the support for the bridle 25 during the pulling operation at the well, the support or cradle I4 can be readily removed by withdrawing the bolts or pins I9. Th cradle may then be lifted from the base It! so that there will not be any projecting obstructions close to the well which might interfere with the pulling or other operation which is being performed at the well. This support will eliminate undue friction and will make it unnecessary to frequently replace the support as is required with the rub-board bridle supports at present in use. Furthermore, by using the single shank which supports the cradle a substantial saving in positioning of the support is effected over the present supports for such bridles.

What is claimed is:

1. A rub-board bridle support comprising a tubular base adapted to be anchored to the ground, a U-shaped cradle, a shank depending from the bight of said cradle and telescoping into said base, means securing said shank in vertically adjusted position in said base, a roller disposed between the legs of said cradle and including outwardly projecting stub shafts extending from the ends of said roller, a pair of bearing blocks for said shafts, and a depending stud carried by each block projecting into the upper end of a leg of 1 said cradle.
